Communication and Cognition of Small Apes thought to be limited to few facial and gestural signals, and their socio-cognitive skills are expected to be rather modest in comparison to great apes that live in socially more complex groups. Research into hylobatid communication largely focused on their songs, with increasing evidence for intra

Gibbon Songs: Understanding the Evolution and Development of This Unique Form of Vocal Communicationions likely contribute to song development. Moreover, remarkable sound propagation of songs is achieved by a specialized vocalism of formant tuning, analogous to human soprano singing. It is plausible that both of these specializations would be adaptive responses to environmental pressures within th

We suggest three key adaptations that were responsible for hylobatids success and survival: (1) perfection of forelimb suspensory locomotion (FSL) including regular, continuous ricochetal brachiation, (2) reduction of group s

Gender and Class in Comparable Worth, it is likely that stem hylobatids migrated northwards from Southeast Asia during the late Miocene, but the Neogene fossil record from this region is poorly documented. Hylobatids occur at a number of Pleistocene archaeological and paleontological sites throughout southern China and Southeast Asia,

Following the middle Miocene climatic optimum, however, the climate changed dramatically. Average global temperature decreased while aridity increased leading to mor

We evaluated the TO-positional repertoire of 24 adult gibbons (11 females and 13 males), and the contextual use of their TO-positional repertoire. Our results indicate that
